The e2e/integration test harness spawns `pnpm-registry` as a faster
verdaccio replacement. CI used to install Rust and build the crate
from source on every test job — adding several minutes per platform.
`@pnpm/pnpr` now publishes the prebuilt binary to npm, and `pnpm install`
already pulls in the matching `@pnpm/pnpr.<platform>-<arch>` package
via optionalDependencies. The Jest globalSetup resolves that binary
through `@pnpm/pnpr/bin/pnpr`'s own module path (the wrapper carries
the platform packages as siblings in its `node_modules`, not on the
parent chain of this file).
- Add `@pnpm/pnpr` to `pnpm-workspace.yaml` catalog and depend on it
from `@pnpm/jest-config`.
- Replace `resolvePnpmRegistryBin`'s `$CARGO_TARGET_DIR` lookup with
`require.resolve` through the npm-installed wrapper. The
`PNPM_REGISTRY_BIN` env var is still honored as an escape hatch for
contributors who want to point at a locally-built Rust binary.
- Remove the "Install Rust toolchain" + "Build pnpm-registry" steps
from `.github/workflows/test.yml`.
